FURNACE WALL.

Application filed October e, 1922. Serial no aearao.

To all wiwm it may concern:

Be it known that 1, MICHAEL LIPTAK. a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Furnace "Walls; and 1 do hereby declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to furnace walls for boiler installations and other places where the walls are to be subjected to intense heat. The present wall is in the nature of an improvement on or modified refinement of the wall disclosed and claimed in several of my pending applications entitled Furnace walls; and, generally stated, the invention consists of the novel construction and combinations of parts hereinafter described and defined in the claims. The present wall structure, like that of my prior applications, involves a permanent outer wall and a replaceable inner 'wall, the blocks of the two walls being inter-connected and supported in a novel manner and by novel means.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a perspective showing a portion of a wall embodying my invention, looking at the wall from the interior of the furnace, some of the blocks in the wall being removed to better illustrate the construction thereof;

Fig. 2 is a vertical section taken approximately on the line 22 of Fig. 1, the parts being shown on a larger scale than in Fig. 1;

Fig. 3 is a horizontal section taken on the line 33 of Fig.' 2; v

Fig. 4 is a perspective showing one of the lintel-forming sections of one of the anchor boxes; and

Fig. 5 is a perspective showing. one of the sill-forming lower sections of one of the anchor boxes in inverted position.

The numerals 15 and 16 indicate, respec- 'tively, the lower and upper sections of tile or masonry anchor boxes in which the sections 15 serve as a sill box and the sections 16 serve as lintels. These blocks constitute parts of the permanent outer wall and they are formed with aligned rectangular openings that afi'ord rectangular anchor pockets 17. Said blocks are preferably assembled to form horizontal belts between which are built in horizontal belts of brick masonry 18. The pocket-forming openings of the blocks 15 and 16 are located nearer to one end of the blocks than to the other, and said blocks are horizontally offset or staggered so that the joints between blocks 15 are norizontally ofiset in respect to the joints between the said blocks 16. In this arrangement the end portions of the blocks afford pilasters that make the wall complete between the pockets 17 ltn the best arrangement here under consideration, the sill-forming blocks 15 are extended outward of the vertical webs of the blocks 16 so that several horizontal layers of bricks 18 may be built therein back of said blocks 16. Also,- preferablyethe stacks of lintel-forming blocks 16 are slightly recessed so that one layer of bricks 18 is set below the extreme tops thereof, see particularly Fig. 2. Advisably, the inner vertical course of bricks 18' are fire bricks, but in walls not to be subjected to very intense heat, these bricks, like the bricks 18, may be common bricks.

As an efficient means for anchoring the permanent wall to buckstays 19, nut-equipped anchor belts 20 are provided, and these between said belts horizontal rows or courses of shelf-forming blocks or long fire bricks 25 placed in groups and extended from the replaceable wall into the pockets 17 of the anchor boxes formed by the blocks 15 and 16. As perterably designed, these shelf-forming blocks 25 have the vertical cross section of commercial bricks but are longer so that they extend completely through the replaceable wall into the pockets 17 but terminate short of the inner walls of said pockets so as to leave clearance spaces 26. To adapt said blocks 25 for interlocking engagement with the sill blocks 15, said blocks 15 and 25 are formed with overlapping interlocking ledges,

interlocked to said sill-formin as best shown at 27 in Fig. 2. To hold the inserted ends of the shelf-forming blocks 25 blocks, k8 y blocks 28 are placed on top t and against the under surface of the sill blocks. Said key blocks are preferably made slightly wedge-shaped and the under surfaces of the sill blocks are bevelled to fit the same. ln the arrangement illustrated, the key blocks 28 do not extend completely through the replaceable inner wall, and the spaces left between the ends thereof are filled in with fire bricks 29. The spaces between the groups of shelf-forming blocks 25, as shown, are preferably filled in with fire bricks 30.

When the shelf-forming blocks 25 are anchoi'ed in the pockets 1'? of the anchor boxes made up of blocks and 15, they aflord shelves that will support the horizontal masonry belts 2d of the replaceable inner wall so that any portion of one of the masonry belts 24 may be removed and replaced without disturbing any portion of an adjacent belt. Also, the arrangement described permits all ofthe parts of the replaceable inner wall, including the shelf-forming blocks 25, to be replaced at will without disturbing the blocks or elements of the permanent outer wall. The clearance space 26 permitsthe shelfd'orming blocks to be embedded further into the pockets so as to loosen the same in case they should become fused to the shelf forming blocks 15. To prevent the outside members of the blocks 25 from becoming fused to the end members of the blocks 15 and 16, clearance spaces are left, as shown at 31, see Fig. 3. To permit the key blocks 28 to be driven out of position from the exterior of the wall by a punch, rod or the like, holes 32- are formed in the vertical webs of the blocks 16 and in the masonry 18, the holes of the latter being preferably bushed with small metal tubes 33.

By reference particularly to Fig. 2, it will be noted that certain of the horizontal courses of common brick of the masonry outer wall extend from the outer surface thereof inward and overlap the tops of the upper sections of the tile anchor boxes.

his gives an exceptionally good bond between the common brick masonry and the upper box sections of the outer wall.

What I claim is: y

1. A wall structure made up of a masonry outer wall and areplaceable inner wall, said outer wall including tile anchor boxesand said inner well including shelf-forming blocks extended into and anchored within said anchor boxes, said anchor boxes being rectangular, the bottom portions thereof affording sills and the top portions thereof atfording lintels and the end portions thereof aflording pilasters in the outer wall, said anchor boxes being horizontally divided and set with their pocket-forming portions aligned but with their pilaster-forming end portions oflset so as to form staggered joints between the upper and lower box-forming sections.

2. The structure defined in claim l in which the lower sections of said anchor boxes project outwardly and support brickwork of the outer wall.

3. The structure defined in claim 1 in which the lower sections of said anchor boxes project outwardly and support brickwork of the outer wall, the brickwork of the outer wall being built in between the upper and lower anchor boxes and comprising brick courses that extend from the outer surface of the outer wall and overlap the upper sections oft said anchor boxes.

4. The structure defined in claim 1 in which the upper sections of the anchor boxes have punch holes through their vertical webs for the purpose stated.
